Thanks for all these additional information.
I understand your concern.
Well I have reviewed your pictures and they don't seem scabies.
Scabies cause intense itching and burrows in skin all over the body and does not appear as bumps and localised to one part of body.
Possible causes may include Folliculitis,fungal infection,HPV infection,Molluscum contagiosum.
You should use OTC Abzorb powder.
Use dial anti-bacterial soap.
You should try OTC 1% hydrocortisone cream mixed with Bacitracin ointment on affected areas.
Also wear loose fitted cotton clothes to prevent friction.
Take OTC Motrin and Claritin.
If your symptoms'll persist then you must see your doctor or dermatologist for further evaluation and management.
Let me know if you have any further query so we can discuss it thoroughly in every aspect.
